玩了几天空之轨迹 FC,终于快结束了。距离最后一门考试还有3天,于是把整个XPath的代码写完了。于是试用一下。
现在展示一下我那个XPath的使用方法:
1 VL_List<VL_XMLNode* , true> Result;
2 VL_XPath XPath(L"//Files//File[contains(@RelativePath,\".cpp\") or contains(@RelativePath,\".h\")]");
3 XPath.Query(Doc.GetRootElement(),Result);
第一行声明一个XML节点列表,第二行构造一个XPath,第三行将XPath作用在一个XML文档的根节点上。这个XPath用于把VC++9.0的工程文件中包含的所有.h文件和.cpp文件提取出来。虽然Files里面包含若干Filter,每一个Filter包含一些Filter和File,不过输出结果Output.xml把所有的满足要求的File节点都找了出来。
下面是完整的代码,包含输入输出、一份vcproj文件和一份结果的XML:
首先是C++代码:
#include "..\..\..\..\Library\Platform\VL_Console.h"
#include "..\..\..\..\Library\Data\VL_System.h"
#include "..\..\..\..\Library\Data\VL_Stream.h"
#include "..\..\..\..\Library\XML\VL_XML.h"
using namespace vl;
using namespace vl::platform;
using namespace vl::system;
using namespace vl::stream;
using namespace vl::xml;
void vlmain(VL_Console& Con)
{
Con.SetPauseOnExit(false);
Con.SetTestMemoryLeaks(true);
Con.SetTitle(L"Vczh XML");
/*设置输入输出文件*/
VUnicodeString AppPath=VFileName(Con.GetAppPath()).MakeAbsolute(L"..\\").GetStrW();
VUnicodeString InputFile=AppPath+L"Input.xml";
VUnicodeString OutputFile=AppPath+L"Output.xml";
/*载入Input.xml*/
VL_XMLDocument Doc;
{
VL_FileInputStream Stream(InputFile);
Doc.Load(&Stream);
}
/*使用XPath对根节点进行搜索*/
VL_List<VL_XMLNode* , true> Result;
VL_XPath XPath(L"//Files//File[contains(@RelativePath,\".cpp\") or contains(@RelativePath,\".h\")]");
XPath.Query(Doc.GetRootElement(),Result);
/*将搜索到的attribute和其他节点分开*/
VUnicodeString OutputAttributes;
VUnicodeString OutputNodes;
for(VInt i=0;i<Result.GetCount();i++)
{
if(Result[i]->GetAttribute())
{
OutputAttributes+=L"<attribute "+Result[i]->GetXMLText()+L"/>";
}
else
{
OutputNodes+=L"<node>"+Result[i]->GetXMLText()+L"</node>";
}
}
/*将结果保存到Output.xml*/
VL_TextOutput(new VL_FileOutputStream(OutputFile,false),true,vceMbcs,true).Write
(L"<?xml version=\"1.0\" encoding=\"gb2312\" standalone=\"yes\"?><result><attributes>"
+OutputAttributes
+L"</attributes><nodes>"
+OutputNodes
+L"</nodes></result>"
);
}
其次是vcproj文件(Input.xml):
1<?xml version="1.0" encoding="gb2312"?>

为了方便,输出并没有使用VL_XMLDocument而是直接构造字符串。
